Final Step: Verification

Once you’ve installed all your code, it’s time to run through your site and main pages (collection, product, cart, and purchase pages) with Google Tag Assistant installed. This will help you troubleshoot any errors.

This appears to be an issue with the shopify_store_country variable (lines 4-9). It isn’t being set for some reason. It needs to be set to the 2 letter country code representing your currency (US for USD, CA for CDN, etc…)

Hello Alex, Thanks for the code. I have implemented the exact code to my Shopify store but I am having 2 issues.
First one – Ad campaign showing the wrong conversions data. For the example – I had 6 conversions today but in total conversion it showing 300. whereas the total click for the day is 200.
And also there are no issues with conviction Value except it is a bit slow to register those values.
Second one – I am getting an error in audience source – Issue: 89% of ecomm_prodid values received don’t match your feed.
In the merchant centre, my product id is like shopify_US_3024029580000_35612608414180.
I have three countries feed in my merchant centre. Do you think this is the reason I am getting this error?

1) In the Google Ads interface, go to TOOLS > MEASUREMENT > CONVERSIONS. This should bring up all your conversion events. There should be a column called “Include in Conversions”. Make sure that ONLY your purchase or revenue generating event is set to “YES”, and that all others are set to “NO”. What is probably happening is that stuff like pageviews or add-to-carts or time-on-site is being recorded as a conversion.

2) This is probably one of the following:
a) You didn’t upload your entire product catalog to google merchant, and so there are products on your website that are not in the google merchant feed.
b) The merchant center product id doesn’t match the remarketing product id (although this is probably NOT the issue for you). But double check to see if the product id generated buy the remarketing code matches that which you have in merchant center (take a look at the country code in product id on your remarketing and make sure it matches some of your products in the feed)
c) You maybe have the remarketing code installed on high traffic pages where there are no products shown (FAQ pages for example). If it’s a page type that I didn’t account for, sometimes the remarketing code will output a product id of “0” which won’t match your merchant center.

Hi Alex, thanks for this detailed and thorough instructions. I have followed your steps and they are all clear to me (except the product variant part in the comments of a Dutch user). However, Google Tag Assistent now shows 3 Tags on normal pages but only analytics tag on checkout. With my code which I had there before, I had 4 tags, including gtag for conversion and remarketing (however they didnt really work well because pruduct.id for remarketing was missing and my smart shopping campaign never started).

Can you help me out? I dont know what to do! I checked the Checkout code severals times now…

When you say “checkout”, do you mean the order complete / thank you page? Or do you mean the order checkout process after the shopping cart?

The issue *might* be the first line in my checkout script: “if first_time_accessed”

This causes the code to only run once per user — so that multiple conversions don’t get recorded — it’s possible you are not seeing the tags because you have are refreshing the same page? Try putting through a new order and checking the tags the very first time the thank you page appears…

I’m trying to set it up for a custom app in a store which redirects the user to another page immediately after the Thank you page is loaded. And in this process, this code isn’t triggered at times. I tried to use “event_callback” property to wait until both the codes are triggered completely and then redirect the user, but it fails when an adblocker is used. How do I proceed with this? Will the beacon method work with your code?

Unfortunately the redirect scenario is not something that I have tested. I don’t think there’s an easy workaround to that other than having a “Your are about to be redirected to another page… Click here to continue” and have the redirect wait 3 seconds or so.

In terms of the ad blockers, that’s unfortunately a reality of the internet in this day and age. More and more traffic is likely to get missed due to Ad Blockers…

Hi Alex!
I don’t really understand HTML code and I have 4 questions:
1. I need to add the Google converting id only one time at the beginning of the code or every time I see “google_conversion_id”?
2. If we use EUR currency, we need to change something in the code?
3. how can I know of the code work?
4. where can I check how many time every parameter fire? like on facebook that you can see in the pixel how many time people went to add to cart page or view_content page or any other parameter?

Hi Ethnasia — I’ve added a set at the bottom of the article to explain how to handle additional currencies. It’s just a matter of replacing “assign shopify_store_country = ‘US'” with your store’s two letter country code. (Currency code isn’t actually being used in the code, it is just a way to determine default store country).

1. You only need to add it once. Replace “123456789” with your actual conversion Id.
2. I’ve added a section explaining how to handle EUR. Simply change the country code from “US” to your own country’s two letter code.
3&4. Install the Google Tag Assistant applet into Google Chrome — it should tell you if you have errors or not. Otherwise the only way is to wait to see if your lists in Google Ads begin growing.

Hi, i get the “Some products are not valid” in Google remarketing tag on the tag assistant. im not sure why, but info: i have 10 products in my google feed for ads. i have over 200 products total. i am checking the tag assistant on one of the products i have in the feed. not sure what the issue is.

another thing: i have dozens of variants for these products but i only have the main variant in my feed and advertised.

Check to make sure that shopify_NL_3069029580900_25312618414180 is indeed in your Merchant center feed and uploaded to Merchant center? Did you upload your entire product feed to Merchant center, or are there some products that you chose not to upload?

You either need to:
1) Change the way your products are being uploaded to Merchant center to use the Shopify style product id (shopify_NL_productid_variantid), or
2) Change my remarketing code to only use the VariantId as the google product id (I think it would be something like: {{ product.selected_or_first_available_variant.id }}

This code attempts to grab the Shopify UserId of the current user on the site, and then passes it along to Google Ads to allow for more accurate user tracking across different devices, etc… Not all Google Ads accounts have access to this feature.
